I built this in the early 1990s. This board which plugs into the C64 user port is basically just a level converter between 5 volt logic levels and RS-232 voltage levels. A reset switch is also included.
TN9 Systen

Inclined uprights and full Height bay dividers to create sectors.
La struttura TN9 consente l'installazione di montanti inclinati e divisori a tutta ltezza per separare vari settori merceologici
Photos from an article about some different identifying marks on chips. You can read that article here.
Changed coefficient DACs to the same modern part I am using for position and limit: MCP4922. Results are slightly more linear but there is still distortion on long lines that I need to track down.
Displayed on Tektronix 604. There is also overwhelming EMI on these signals that I haven't tracked down/suppressed.
The PCBs for my nixie tube clock arrived, and I even got twice as many as I ordered! Hurrah for Gold Phoenix.
At any rate after a marathon soldering session they are finally assembled and awaiting testing and programming and all that. The power supply works, and the AVR was programmable, so that's a good sign!
My lifelong quest to get electrocuted continues.
This is an electronics proof of concept for a table lamp that I want to make, it's called "North" and is brighter the closer it is pointing to north.
I was also, rather self-centeredly, thinking about making one that burns brighter the closer it is pointing to the place where I was born, a hospital in Stockholm, although the idea would be that a person would choose a place that means something to them personally, whatever it is.
I'll have to get a little GPS module chip and see if it could work.
Usability wise where the lamps needs to point doesn't really matter as all you would be looking for is to get the right level of light.
Here are the stats: We collected 19lbs of recycling and 87lbs of trash. The crowning highlights found were, an alligator, Elsa doll, and a yellow bird stuffy.
Happy Earth Day Everyone!
I just found this on the global site of LG Electronics (http://www.lge.com/general/lg_globalsite.jsp). This map links to the separate LG country sites, sorted by regions. Call me a total nerd, but check this out:
Instead of a reunified Germany, I'm seeing a thick border still running between former East Germany and West Germany (I grew up in East Germany, and I can testify that the reunification did happen.....17 years ago); instead of the Czech Republic and Slovakia, I still see the former Czechoslovakia (which ceased to exist more than 14 years ago...); the CIS is not a nation, it's a commonwealth of sovereign states - the LG map shows the former Soviet Union including the three Baltic states (that never belonged to the CIS but are members of the European Union) and Turkmenistan (which withdrew from the Commonwealth of Independent States in 2005). And: Since there's no separate LG country site for Iceland, I'm not going to mention that Iceland actually belongs to Europe and not to North America (Iceland gets tinted, too, when you roll over North America).
It appears that LG doesn't seem to acknowledge the global political situation after 1990. Sweet, sweet Cold War.
I actually kinda like these little bugs on the map if they just weren't of such a scandalous shame for a global company like LG. Nonetheless I tried to send them a mail thru their "Contact Us" mail form to suggest a slight revise of this map (hint, hint!), but their mail form was so badly coded that - after trying three times - I wasn't able to deliver the message to LG.
So let's just leave LG as the Sleeping Beauty and enjoy the good ol' times before the events of 1989.

A little programmer carriage for an 8-pin ATTiny chip. It's basically just an ISP header and a DIP socket.
They arrived today from Russia!
All twelve are in great condition considering that they were made in mid 1980 - they were packaged very well, foam covering some kind of milk-thing-box from Russia which contained more foam wrapping the actual tubes. The tubes are 2 inches high from bottom of the glass to the top, and the characters are 2cm high. Tubes from tubes-store.com/ who still have loads of this type (IN-14) left.
Once I've got some free time I'll turn these into a clock, but first I have to figure out how to generate 170V DC...
We came across an interesting oddity from the realm of consumer electronics: a fake seven-segment LED display. Just for fun, we made our own version too.

I went for the danger option and added one more nixie, bringing it up to four. Of course I had to have them display 1337.
Looking inside the metal box you can see the deep cycle battery, charge controller, power supply, and the computer with the custom circuit to turn on/off the computer when the sun is out. On the right is the La Crosse weather station.
